Build notes:

iRACING UI:

————————————————————–

Launching

A “Couldn’t Connect” message will now be displayed at the Splash Screen if a user fails to reach the application or it was not reachable, instead of getting stuck on the Splash Screen.

Create a Race

The maximum number of different car models selectable for a Hosted Session has been increased to 12!

Results & Stats

The Results page has received an overhaul for improved usability.

– – The Results page now includes a fully featured “Find Past Results” button, which opens a modal window with several selectable fields and filters to help you find exactly the sessions you want to see.

– – – – For Official Racing, you can search and filter by participant type (Yourself, Friends, Follows, or Driver search), Date Ranges, specific Season(s) or Week(s), License Type, and Session Type (Race, Practice, Qualifying, Time Trial).

– – – – For Hosted Racing, you can search and filter by Participant Name, Session Name, Host Name, or Team Name, Date Range, License Type, Car, Track, and config.

– – – – Oh, and you can still search by valid Subsession ID if you want pinpoint precision.

– – The Results page now includes two tabs, one for Official Racing and one for Hosted Racing to help divide the displayed results.

Paint Shop

New sponsors have been added to the Paint Shop!

– – ImSim

– – Sim-Motion

SIMULATION:

————————————————————–

Payments

Effective September 5, 2023, in order to simplify and streamline payment options, PaymentWall is no longer a payment option for iRacing.

– – For more information on our payment options that are available, please visit https://www.iracing.com/resources/accepted-payment-methods/

Updater

Fixed an issue that could occur with the installation of the EasyAntiCheat (EAC) cheat prevention software if another game on the user’s system already had installed a version of the EAC software.

Official Series Schedule

The schedule PDF now notes whether penalties or disqualification for too many incidents is in effect for the series, and the incident count thresholds.

Optimization

The entire memory allocation system for iRacing has been analyzed and optimized, for improved loading times, and faster processing speeds.

The worker processing thread pool allocation algorithms for all types of hardware have been improved, especially those of Enki worker threads.

– – This replaces some temporary fixes that were aimed exclusively at hybrid CPUs.

Improvements have been made to the methods by which the iRacing Deferred Rendering Lists are generated and sorted, yielding some modest CPU render time improvements.

The memory footprint requirements for audio files has been reduced by over 65% while maintaining audio fidelity.

Track reference lines for each car class within a Session are now loaded synchronously instead of sequentially. This improves track loading times for multiclass Sessions by a factor based on the number of car classes in use.

Loading

Fixed a Simulator crash that could occur during the loading transition from an Open Practice to a Race Session.

Cars

The methodology for processing anti-lock braking systems in the Simulation has been updated.

Tires

Rolling drag has been rebalanced for off-track surfaces.

– – This change should provide a much more realistic experience for grip and momentum when driving on grass, sand, gravel, grass-crete, and other off-track surfaces.

Race Control

Several penalties have been changed from Stop-and-Go penalties to Drive-Through penalties.

– – Minor Pit Exit Checkpoint failure penalties are now drive-through penalties.

– – Pass Inside penalties are now drive-through penalties.

– – The Jump Start rule for standing starts has been updated to begin as a drive-through penalty for a minor offense, but can be upgraded to a stop-and-hold penalty for a major offense.

Dirt Racing

An expansive round of fine-tuning has been completed for Dirt Racing as a follow-up to the 2023 Season 3 Dirt Refresh project. These changes include:

– – The variability for the starting dirt track state has been increased. This includes variance in dirt heights, density, and water content.

– – The dirt track surface wear rate has increased slightly.

– – Improved the tracking and recalculating of the dynamic track based around dirt that is thrown around the track from tires. This should slightly increase the wetness of areas as more dirt is added.

– – Dirt coloring has been updated slightly based on water content.

World of Outlaws 2023 contingency decal packages have been updated for the associated vehicles.

Qualification Scrutiny

The Qualification Scrutiny system has been updated to prevent drivers from driving into the pits during Qualifying to gain an unfair advantage.

The Qualification Scrutiny officials are now able to detect attempts to adjust qualifying time by traveling in reverse in the pit lane.

Spotter

A variety of brand new spotter messages have been added to the default iRacing spotter functionality! These include the following:

– – INCIDENT OR OFF-TRACK: Your spotter will tell you when an incident has occurred nearby, or a car has gone off-track nearby.

– – – – These new spotter calls only trigger for asphalt Road racing.

– – – – These new spotter calls only trigger if the offending car is at a delta between 0 and 5 seconds ahead of you, or is within 3 seconds behind you, or is the race leader for your class.

– – – – Only 2x or greater Incidents are reported, and if multiple issues occur at nearly the same time, these new spotter calls only inform you of the largest offense.

– – – – Only one of these messages can trigger every 10 seconds.

– – – – These spotter calls do not trigger if you are in the pits.

– – DAMAGE AND REPAIRS: Your spotter will tell you about the type of damage you have sustained and how your team will be able to address it.

– – – – While towing, your spotter will share information about Optional and Required Repair times.

– – – – Your spotter will also inform you about predicted remaining damage (if any) after repairs are complete.

– – – – While repairs are ongoing, your spotter will inform you when you have 30 seconds of repair time remaining.

– – – – If you received race-ending damage that cannot be repaired, your spotter will also unfortunately inform you of this.

– – – – You can request your crew chief tell you your current damage level by using a new Spotter Damage Report keybind.

– – RACE ENDING SOON: Your spotter will tell you when there is either 5 laps or 10 minutes remaining in the Session, whichever comes first.

– – – – This call does not trigger if the event is less than 20 minutes or 10 laps in length.

– – STRENGTH OF FIELD: At the start of an event, your spotter will provide you with insight based on the calculated strength of field for your car class.

A variety of new entries have been added to the “app.ini” file to control if some of the new Spotter messages will play for you, and/or certain parameters such as intervals and decimal accuracy.

– – The default state for all new spotter calls is “ON”. You will need to launch the Simulator once after updating before these entries will appear for you and may be customized.

Spotter – Foreign Language Packs

The Italian Marco Arcidiacono spotter pack has been updated.

– – Grazie mille, Marco!

The Italian Renzo A Olivieri Spotter pack has been updated.

– – Grazie mille, Renzo!

The Spanish Ari Cejas Spotter pack has been updated.

– – Additionally, the feminine form of this pack has been removed, and it has been made gender neutral.

– – Muchas gracias, Ari!

Pit Stop

Fixed an issue where the Fuel Fill checkbox did not respect the “autoResetPitBox” value set in the “app.ini” file.

Auto Fuel System

Fixed an issue where the Auto Fuel System could sometimes fail to calculate the correct fuel needed to finish the race in situations where the player is multiple laps down and would not be able to finish the full race lap count.

New Damage Model

The New Damage Model has been enabled for 13 new vehicle models!

– – Acura ARX-06 GTP

– – Dirt UMP Modified

– – Ferrari 296 GT3

– – Ford Mustang FR500S

– – Modified – SK / NASCAR Whelen Tour Modified (Modified – SK, & NASCAR Whelen Tour Modified)

– – NASCAR Classic Pontiac Grand Prix – 1987

– – NASCAR Xfinity Class Cars (ALL THREE models)

– – Porsche 963 GTP

– – Super Formula SF23

For Ghost Cars, fixed an issue where their ghost tires could take ghost damage, which could make them extra ghostly and appear to fall through the earth a short ways before resetting above the ground. Spooky.

Graphics

When Graphics Auto-Config is run, an additional hardware check has been added for memory size and cores. If our check detects your system is below our minimum recommended system specs, a warning notification will appear to let you know you may have difficulty running the Simulator.

– – You can find our current minimum system spec requirements and our recommended system specs here: https://www.iracing.com/membership/system-requirements/

Improved the initialization process for devices using OpenXR.

Improved the appearance of lit transparent particles.

Fixed some issues with inconsistent track surface decal rendering.

Fixed an issue with the rendering of metals with HDR, where they were appearing too dark.

Fixed a resolution issue with heat haze rendering.

Fixed an issue where disabling Triple Projection caused graphical artifacts.

– – This issue was impacting any post-processing effect that utilized the velocity texture, such as SMAA or motion blur.

Fixed an issue with stutters seen when running Varjo software alongside a hybrid CPU or a processor with more than 16 logical processors.

Fixed an issue where some particles could appear to have an incorrect brightness at tracks where stadium lights were in use.

Some legacy DirectX 10 shader code has been removed for improved SpeedTree performance.

Visual Effects

Fixed an issue where distortion particles were only appearing in one eye in VR.

3D Foliage System

Mother Nature has arrived at three more tracks:

– – Circuit de Lédenon

– – Circuit Zandvoort

– – Sebring International Raceway

– – These environments will now be populated with a variety of grasses, shrubs, flowers, and other low-lying plants native to their area of the world.

– – Remember, 3D foliage has no impact on driving or physics, but should decorate the world much more realistically. In the Graphics Options menu, there are several levels of detail that may be selected for use by the 3D Foliage System which can customize your visual experience and your rendering performance. You may also select to disable the system entirely.

Some generation parameters have been adjusted to reduce the likelihood of vegetation spilling over the edges of the terrain onto track surfaces.

Color scaling and foliage blending have been implemented.

Improved some foliage rendering processes for slight GPU gains.

Audio

A new Audio Option, Ear Protection and Helmet Effects, have been added to iRacing!

– – These new settings apply an audio filter to the Simulation which mirrors the effect of various forms of ear protection often found at the track. Each applies a different audio algorithm to all sound being played in the world for a more authentic experience.

– – These settings are found in the Sound Options page, and are named “Ear Protection / Helmet Effect”. Selectable effects include:

– – – – Ear Plugs

– – – – Earmuffs

– – – – Open-Face Helmet

– – – – Full Helmet

– – This feature is only available if XAudio2 is in use.

– – These audio effects only occur when the camera is set to be in the driver’s perspective.

Removed “None” as a device selection default for Spotter and Voice Chat. These now simply use the system default which functions normally.

Fixed some resource leaks where switching to and from audio systems were not cleaning up after themselves, and could leave sounds hanging in the aether.

The XAudio2 library has been updated from 2.7 to 2.9.

Force Feedback

A new “Intensity” slider has been added to the Driving Controls options screen. This slider replaces the “autoForceFactor” setting value, previously found in the “app.ini” file.

– – This controls how the Force Feedback auto button (found on the F9 black box) behaves. With the slider set to 100% it behaves as it did last season, giving you the maximum force that your wheel can produce. With the intensity slider set to 0% it will attempt to both lower the forces as well as give you some variation from car to car so cars with higher Force Feedback will feel heavier.

Fixed an issue that could cause the Force Feedback system to send an invalid signal, if the wheel no longer reports its position accurately.

Pace Car

The Sedan Pace Car texture color has been improved.

Sporting Code

Updates have been made to the Official Sporting Code for the 2023 Season 4 Release. These include the following:

– – Section 5.4. Divisions, has been completely rewritten for improved clarity.

– – For section 9.2.2., more clearly defined where the Official Protest Form may be found.

– – For section 13.1.3., updated the language for gridding cars that did not post a Qualifying time during a Multiclass Race.

– – New Glossary entries have been added for: 3D Foliage System, Active Reset, Auto Fuel System, Force Feedback, and Telemetry.

– – Other minor fixes.

This car includes an Overtake system, which is only available during Race Sessions.

– – Debuting in the 2023 Super Formula season, the SF23 is the third open-wheel car developed by Italian manufacturer Dallara for Japan’s premier open-wheel racing series. From a visual standpoint, the SF23 evolves from its predecessor by introducing new aerodynamics designed to produce more overtaking. From a sustainability one, the new design reduces carbon dioxide emissions in raw materials and manufacturing by 75% thanks to new, natural materials, while even the Yokohama tires used on the car use significantly more renewable raw materials while maintaining the performance of previous tires. Super Formula cars are powered by high-performance, turbocharged 2.0-liter I4 engines, each capable of producing more than 540 horsepower. Each is equipped with an Overtake System (OTS) that allows for up to 200 seconds of additional fuel burn in each race.

Autodromo Internazionale Enzo e Dino Ferrari

Graphics cubemap used at this track has been improved.

Circuit de Lédenon

NEW TRACK!

– – A new Road racing track, Circuit de Lédenon, is now available for purchase and racing!

– – Breaking ground in 1970 and opening three years later, Circuit de Lédenon is one of France’s most unique and challenging race circuits. Measuring in at 1.958 miles (3.151 km), the track manages to pack 13 varied corners and plenty of altitude changes into a relatively small space. It also differs from most other major tracks in France in that it runs counterclockwise. The track had played host to French Formula 4 regularly since 2011, and also hosts national GT races. A lap at Lédenon begins with the long, high-speed frontstretch before entering the Triple Gauche, three left-hand corners that lead into the Virage du Pont, a tighter right-hander. After the slow La Carrierrasse left-hander, drivers accelerate through La Courmelle and downhill into the Virage du Camion, before Le Cavalet turns them hard right and uphill once again. After getting through La Servie, drivers accelerate through one more straightaway broken up by smaller corners before La Cuvette sends them back onto the frontstretch.

Circuit Zandvoort

NEW SCAN AND FULLY UPDATED TRACK!

– – A 2023 scan data and fully rebuilt version of the Road racing track, Circuit Zandvoort, is now available for purchase and racing!

– – This 2023 version includes four track configurations: Grand Prix, Grand Prix w/ Chicane, Nationaal, and Oostelijk.

– – Circuit Zandvoort ranks among the most historic and challenging road courses in all of Europe. Home of the Dutch Grand Prix from 1952 to 1985, and again since 2021, Zandvoort features a testing blend of straightaways, tight, medium and high-speed turns that run over and around the sand dunes just a few hundred yards from the North Sea. Designed by John Hugenholtz, the Zandvoort circuit opened in 1948. The 2.6 mile road course, located west of Amsterdam, boasted a couple of signature corners, including the fast and undulating Scheivlak, and Tarzanbocht a slightly-banked 180 degree turn at the end of the long pit straightaway. Coupled with the heavy braking at the end of the straightaway, the modest banking encouraged overtaking maneuvers, the most famous of which resulted in Mario Andretti and James Hunt banging wheels during the 1977 Dutch Grand Prix. Over the years, Zandvoort witnessed many classic races. In 1959 Jo Bonnier scored B.R.M’s first Formula One victory there. Eight years later the legendary Ford Cosworth DFV earned a famous win in its competition debut in the hands of Jimmy Clark, one of four Dutch Grand Prix wins for the Scotsman. The rain-swept ’71 Dutch Grand Prix featured a showdown between the two great rainmeisters of the day – Jacky Ickx and Pedro Rodriguez – that was ultimately resolved in the Belgian’s favor. A partial list of Ickx’ fellow Dutch GP winners includes Alberto Ascari, Juan Manuel Fangio, Stirling Moss, Jack Brabham, Jimmy Clark, James Hunt, Alan Prost and Niki Lauda. Following the 1985 Dutch Grand Prix the circuit closed owing to financial problems. It reopened four years later as Circuit Park Zandvoort and featured an abbreviated (1.6 mile) version of the original track for use in club racing. In 1995, however, the Dutch government gave the CPZ the go-ahead to develop a new international level circuit. The resulting facility opened in 2001, featuring a modern pit complex as well as the old Tarzanbocht and the new Arie Luyendyk-bocht, which honors the two-time Indianapolis 500 winner who cut his racing teeth at Zandvoort. The contemporary Circuit Zandvoort boasts four different configurations ranging in length from 2.64 to .87 miles. It was reconfigured and brought up to modern standards in anticipation of hosting the Dutch Grand Prix once again in 2020, though the COVID-19 pandemic postponed that for a year. In addition to a full slate of amateur and club races, Circuit Zandvoort annually hosts rounds of national and international sports car races. The iRacing package of Circuit Zandvoort includes both the current version of the track, reflecting its FIA Grade 1 status, and iRacing’s original scan, which features five layouts.

– – Customers who purchase Circuit Park Zandvoort will automatically be granted ownership of this version of the track.

Kern County Raceway Park

NEW TRACK!

– – A new track with both Asphalt and Dirt Oval racing, Kern County Raceway Park, is now available for purchase and racing!

– – This track includes four track configurations: Asphalt Track, Legends, Dirt Track, and Dirt Mini Oval.

– – One of California’s most unique racing playgrounds, Kern County Raceway Park opened in 2013. The track was built about 30 miles west of the former Mesa Marin Raceway, another half-mile paved oval that held races from 1977 through 2005, including nine NASCAR Craftsman Truck Series events. Alongside the paved oval, which is a regular host of the ARCA Menards Series West and other stock car events, Kern County also has a third-mile, asymmetrical clay oval for sprint car and midget racing. Kern County’s paved oval features progressive banking in the corners, starting at 12 degrees at the bottom of the track and rising to 14 degrees at the top, as well as eight degrees of banking on the straightaways. Turns 1 and 2 are raised slightly higher than the straightaways and Turns 3 and 4. The corners are also different on Kern County’s dirt oval, with Turns 1 and 2 of that track tighter than Turns 3 and 4.
